The book by historian Yu. Tsurganov is dedicated to an exceptionally difficult page in the history of the Russian diaspora: attempts to take advantage of the outbreak of World War II to overthrow the Bolshevik regime in the USSR and bring the national Russian government to power. The collaboration of Russian emigrants with the Nazi regime is the most tricky aspect of the history of the anti-Bolshevik movement, so the author is especially careful in covering it. Yu. Tsurganov pays special attention to the clash of two anti-Bolshevik “civilizations”: the old Russian white emigration and the flow of former Red Army soldiers who were captured during the first period of the war. The organizational formation, development, interaction and interpenetration of these two trends is one of the main themes of the book. The work is written on extensive documentary material from Russian and German archives, with the involvement of a wide range of published sources.
